Extinction is the permanent loss of a species from the planet, meaning that no individuals of that species remain alive. It occurs when the last remaining member of a species dies, leading to the irreversible end of that species' existence. Extinction can result from various factors, including habitat destruction, climate change, overexploitation, disease, and invasive species.
The process can happen gradually over time or can occur suddenly due to catastrophic events. Extinctions can have significant ecological consequences, as they disrupt ecosystems, food chains, and biodiversity, ultimately affecting other species and the environment.
